Abstract

La presente invencion se refiere a metodos y un vehiculo para mejorar la deshidratacion mecanica de un lodo. En un aspecto, la invencion se refiere a un metodo para la deshidratacion mejorada de un estanque de sedimentacion con un vehiculo de deshidratacion mecanica que incluye: medir una o mas propiedades de un lodo a depositar en el estanque de sedimentacion; determinar un perfil de flotabilidad para el vehiculo, basado en una o mas propiedades medidas y una o mas propiedades del vehiculo, de manera que el vehiculo tenga una flotabilidad neutra en el lodo cuando se deposite en el estanque de sedimentacion; y determinar una profundidad de lodo optima para que el lodo se deposite en el estanque de sedimentacion de modo que el vehiculo pueda mantener una traccion sustancialmente libre de cizallamiento cuando el vehiculo atraviesa el lodo.The present invention refers to methods and a vehicle to improve the mechanical dehydration of a sludge. In one aspect, the invention relates to a method for improved dewatering of a settling pond with a mechanical dewatering vehicle including: measuring one or more properties of a sludge to be deposited in the settling pond; determining a buoyancy profile for the vehicle, based on one or more measured properties and one or more properties of the vehicle, such that the vehicle is neutrally buoyant in the mud when deposited in the settling pond; and determining an optimal mud depth for the mud to settle in the settling pond so that the vehicle can maintain substantially shear-free drive as the vehicle traverses the mud.
